Had a play about with the cooling system this afternoon, not sure how viewable the image will be but here goes.... Good to see some data from testing. This was all done at tickover? What is the reason or thoughts for this? Will you also do the same tests with load?

Not sure how relevant this is, but I swap engines in and out of the LC's now and then. I put a little two stroke oil in the cylinders, make sure that all in and out holes are blanked off and pour engine oil or flushing oil into the crank space until it quite full.

You can also try Heidenau brand. I've heard lots of positive remarks from the classic bike racers about them. I've got a set on std rims but have only done 400 miles on the road. So can't really comment much on them.
Bridgestone S21's and S22's I like alot, but they wear out quickly. I am just about to order some R10's or R11's in a H rating if I can find them. I've used the V rated R11's on a 443cc powered bike with no complaints. They warm up quickly.

Collected this Beauty from Dave at Mutts Nuts!! 421!!! by Keith Tiplady, on Flickr It wasn't today but on Friday the utter god that is Dave Whattam ran the motor back up for me, very pleased with that chart!!! 421 dyno by Keith Tiplady, on Flickr Nice power output. That's definitely not in the LC Caravan Club!

My favourite design is from Randy Mamola.
I also like the Caribbean style sun with the smiley face. Similar to a few of Rossi's designs. I still can't forgive him for making flurescent yellow/green colours popular.

Gotta be my AGV Kenny Roberts replica Pity it’s too old to use now. I keep thinking of having a new helmet painted up the same, but it’d cost too much Do it Bill We only live once.

I have made polyurethane parts in the past and it was always a bit hit and miss with the shore once made.
Sometimes too hard and sometimes too soft using the same resin/compounds. The mixing seems to be very critical Do you know what the ideal shore hardness would be? No sorry i don't but i could try to measure it for you if the meter is in the company workshop.

A set of early R6 (right way up) forks gives you a nice comfy ride which i like on my road bike, Plus i found out early R1 upside down forks will bolt straight in. Never used them, so can't comment on how good that set up is.

My personal experience and preference is to adjust the flow so that you have no more than 1 degree maximum temperature difference between entering and leaving the engine. That is without a thermostat in the system. Is that at tickover? No running temperature. It is a bit of a juggling game which also has a lot to do with the efficiency of the radiator. But aim for a degree max when running at shall we say 7000rpm. You need good flow through the engine or it will get hot. Standard pump is good enough. Think of the radiator like a river. Big river slow flow small river faster flow, the bigger the radiator generally it will flow slower. The in out temperature of engine is important.

I see. I use non insulated connectors and only solder the clip bit not the strain relief bit. So in theory the wire still remains flexible from the connector end. Jon Hi Jon i use non insulated connectors an then insulate them with the correct plastic sheath. I'm not really to savvy when it comes to Electrickery. There are so many different types of connection blocks to choose from, i always wonder which is the best type. To be honest i really don't like those coloured plastic connectors and only use them when i have no other choice. In the past i have had a small bollocking via PM about my wiring from a member here. I always look up to him so 9 times out of ten i listen to him and take his advice very seriously.

In The past i have read not to solder connectors on vehicles etc. Personally i thought fussy buggers. My Bakker bike creates more vibration than a standard bike and the only wire which i soldered failed. Maybe just coincidence but i try to avoid soldering now. Purely out of interest which wire was it? Jon It was an earth connector from the rpm meter to the chassis i used an old connector which i cut off another wire and soldered it.

Actually when i think about it we use and aluminum gasket material which is made up of lots of thin layers. You fit the component onto the engine measure the clearances then remove the component and peel the layers away until you have reached the correct tolerances. A bit too "over the top" for this sort of repair.

The Engine case Al has was the first one i did. Thank you for the nice words but you still need to fill in a few pits etc. A few years back Norbo offered a load of scuffed up cases for sale or a trip to the tip with them. At that moment i was in clutch mode and thought i could use them for dry clutches. They were mostly 4L0 cases. Fast forward a year or two i made some jigs for making dry clutches easy to make with out spending (expensive?) time aligning components on lathes and milling machines. Apart from the water and oil pump differences, there are other differences between the YPVS and 4L0 cases. Basically the 4L0 case is thinner/more delicate compared to the beefier YPVS case. It just so happens that one of the jigs is also good for road rash repairs. Still not that easy to do because you have to take distortion into consideration. So far no complaints from the other two people i have helped. Luckily not forum members so no spotlight .

I don't see any problems with using a spacer. It might come in handy as you can adjust the cylinders to the correct height depending on their condition and state of tune.
A very good sealant to use once you have the correct height etc. and are in the final build process is Loctite 5910. If i ever get a bad leak difficult to cure this is the stuff to use. Just one small problem with this stuff is it can be difficult to part the components when you need to strip them back down.

I've never owned that many bikes, but the worst bike for me was a Yamaha XS850 tripple. I swapped a Honda XL650 for it. I was in Australia at the time and i kept breaking the the Honda cylinder head(s) so swapped it after i repaired it. At that time in Ozz they would repair the roads and just make a dirt track next to the road. These dirt tracks were kilometers long and i could drive just as fast on the dirt track as on the road with the Honda. The XS was another Kettle of fish. On the road it was heavy to turn and felt very lardy compared to the Honda. On those dirt roads it was like "an ice skater on LSD" very scary and you had to slow down. For some reason to this day there was still something i liked about it (not sure what it was). I still like the Gpz 900r i have now joined a forum but have never posted yet. Just liked them ever since i saw one. I think it's that Darth Vader look. Unfortunately i have been seduced to the darkside, my bike is not fast enough and i need to turbocharge it. That's a long way off maybe more dream than reality. I do have a spare turbo charger for the Land Rover I wonder if that will fit?

Yes I have repaired a couple now. They are still not perfect but everything was a little better each time i did it. First the gravel rash cleaned up and then welded. Second the welding is machined to suit the rest of the case. The most important part is preparing a good surface to weld onto and then make sure you put enough weld on. I think this method is not cost effective when you consider the effort and material costs involved. Plus still a bit shonky.

hello Tony yes i did but at the time the bike needed setting up and , added to the fact that i wanted to fit some NK rear sets it got sent to Mutts maestro Dave and had some pipes made to suit the hangers , but even with the bike not running well at low revs or idle the hydroformed pipes was alright but it was a bit topendy and i am fairly sure if iirc there was no difference in rwhp (0.1) between the hydro pipes and the Alonze ones once Dave set it up just to add the Hydroformed pipes look great in my eyes mart I always loved those pipes in black chrome. I think i might have made a tight ass bid to Dusty for the pipes. i should have offered more!

I have got a set of good standard barrels now so I will probably try both and sell whichever I don’t want. What would be a sensible price to ask for the tuned barrel. Sensible answer please, I am not giving them away 😉 About the same price of the cylinders you just payed for.

It’s a shit design. They should have moulded it around a hexagon rather than splines IMO. It makes me wonder if the impellor is actually moulded around the splines shaft, or it’s heated up and pressed into the plastic? Any witness marks? Jon Yes witness marks on the inside of the steel cover. Not much as it didn't run long as i was monitoring the temperature with a Raytec. This one is threaded and came loose on the thread. Its now fitted with another old original impellor. All back together now. If the weather is not too shitty i might start it tomorrow. I need to make some better pictures of the pipes. They are noisy as bugger and look a bit like Allspeeds with JL cans. It makes me wonder if they are a hybrid pipe or original design?

From your pictures and measurements they are a very good set of cylinders and much more desirable than standard in my eyes. They will be a good all round performance enhancement.
It could be a repair but i've seen welding performed on parts before the start of machining or fettling of the parts to keep it stronger or stop any breakthroughs.
Don't sell them as crappy cylinders.

“First I need to find out why the water pump ain't working.” The water wasn’t working properly on my 250LC. Turned out to be the impeller spinning on the splines of the shaft. Wonder if yours is the same? Jon Yes Jon the impeller is loose. Happy days easy fix. I'm glad it was nothing to do with the cylinder head. As you can see it's an aftermarket part. It's difficult to beat original spares unless you are heavily modifying your engine.

Mi too but will be using molycote 111 on the threads Use it at work as a peristaltic tube lubricant but excellent for stopping stainless galling Found when doing up m4 SS bolts with a cordless driver if you went too fast the stainless would generate enough heat to lock them solid Steve Yes i use it on titanium bolts, also brake components.
