Hi Davey, Good question, but I dont know the answer, hopefully someone will know,.... do you get different small can Allspeeds for 4L1 4L0 and YPVS ?... Im also asking as mine are stamped "350" They are a bit worse for wear, but Im hoping to have a go at tarting them up, and getting them on for next year. Cheers, Steven.

... Here is a pic of the 6.5 x 11 purple stuff fitted with the clips I found on ebay, obviousely Elsie still had her yellow clothes on three years ago. I think they only did the purple stuff at the time I was looking for it, so mabey the 5.5 stuff will be a tighter fit, Iv had no probs with any leaks or anything so far with the 6.5 stuff and those clips. cheers, steven.

.... I used the 6.5 x 11 purple stuff, fits fine. I found appropriate clips for it all on ebay, but not standard ones. Sorry Shaun, no idea about the oil pipe, as I run premix.

Love to see him on a lc/ypvs😄 ... He,s no getting a shot on my LC !... he blew that Beemer up in practice then crashed it while racing !

When using bearing lock glue make sure that it is the correct type There are different types for different tolerances ....and it has a shelf life.

Wow, heavy duty crank shaft phase checking thread ! but all very interesting reading how others do it.
I have just done 16 hours work in the last 24 hour period, so perhaps not the best time to think about all this.
The comment.... "you do not need to find TDC, but only where the piston is at it's maximum height" threw me a bit....when the piston is at it,s maximum height, that is TDC !?!?!... is it not ?
So, obviousely lots of different answers on how to check the phasing of your crank shaft. I understand that we all use our LC,s for different things, some like to race them and get every last ounce of power out them, and some like to tootle about the back roads on them on a sunny day, I fall into the latter group.
I agree with the above comments that the only 100% sure way to check the crank properly is with it out and on some V blocks etc. But personally, on my 36 year old 2 stroke twin with its 180 deg crank shaft, I find the level of accuracy gained with two clock gauges poked down its holes more than adequate for my requiremnts, especialy if the alternative is pulling the crank shaft out it !
If its out by a measureable bit the clock gauges will show it up anyway, and if its out by a wasps wing, that my clock gauges dont show up, I,ll probably be none the wiser and still enjoy my sunny days runs around the back roads, feeling that all is well with the world.

Another method would be to set the left cylinder with a dial gauge to 27mm (half standard stroke) from TDC and check if the right is the same. If not, the crank is twisted! :-) This would allow for dwell. ....you are still going to have to find TDC as your datum/starting point with this method, to then set 27 mm before or after TDC, so you are still going to incur the "dwell" that Bare mentions. As said previousely, a clock gauge/DTI and a rod/pointer/stick down the plug hole is the approved method for finding TDC, not only by Yamaha, but various other engine manufacturers. steven.

... Knew I had the pics somewhere, here is the set up I used, Im always paranoid the crank twists when I tourque up the alternator/ignition rotor, so I made this afair up to check mine with two clock gauges. I cut up some spark plugs, and machined them out to accept some silver steel bar that is a nice sliding fit. Bare, I hear what you are saying about a dwell at TDC, but if there is a dwell at TDC there will also be one at BDC, wont there ? In practice, it is minimul and TDC/BDC can be acurately found using two clock gauges. If this method of finding TDC is not acurate, how are you going to acurately set your ignition timing ? With the engine assembled, is there an any more acurate way to find TDC than the above method ? Using a timming pointer like the ones I made up, is the approved method for finding TDC and setting your static ignition timing, which then allows you to set the ignition/alternator backplate with the fixed index mark, which is then used to check your dynamic ignition timing with a strobe. Yamaha even list a set up scimilar to my home made afair for finding TDC, it mentions the Yamaha part numbers of the gauge and pointer etc in the Haynes manual, but we all knew that anyway. Im off to bed now, I hate night shift ! steven.

With two clock gauges. When one piston is TDC the other one should be at BDC. I have photos somewhere I will dig them out.

Hi, My understanding of the reasoning behind mass produced 2 strokes leaving the factory with rather large squish bands is to do with the problems encountered with tollerances on mass produced parts.
ie, if the tollerances on con rods and pistons is at the upper end of the tollerance, and the cylinder is at the lower end of its tollerance, then there is a danger of the piston hitting the cylinder head. So, manufacturers delieberately make the squish band wide to make allowances for the worst possible parts size combination.

Hi Steve, I dont know anything about it, all I know is what Im reading online. Im reading about 750,s which are really 900,s and something about "internal political unrest" and the technical guys insisting on inspection, when in the past, teams have been told there will be no inspections. Seems to be plenty other stuff going on, plenty scandall to be read about here...... www.facebook.com/permalink.php?story_fbid=1155765224479625&id=175266482529509

Hi, If you post a few pics, that might help us to help you a bit better. If it has been fitted badly/wrongly in the past, the lugs on the drive plate can get bent, and then wont engage with the speedo drive. There are two cutouts on the wheel too, that the speedo drive plate engages with. You can prise the old seal out easily with a screwdriver or something like that, if you are careful, you could probably re use it, but new ones are readily available, Im sure Norbo will have them too.

... Glad to report that Elsie is MOT posative for another year. I had a great day out in the sunshine, and was out on it last night too for a quick test run as I knew it was going for its MOT today. I dont know when last I was out on it two days in a row ! Again, I have not done as many miles on it this year as I had hoped, but it is nice to know it is sitting there all ready to go when ever the notion takes me. The novelty is starting to wear off in the fact that EVERYWHERE you go or stop on it, someone is up at you with the "I used to have one of them" or "Iv not seen one of them for years" and wanting to stand and reminisce about LC,s, it usually doesnt bother me, but today it did for some reason, the joys of owning an LC I suppose. The pic of the big TV mast is Darvel Transmitter, where our telly comes from where I live in Southern Scotland, its nice and remote and quiet up there. When taking that pic, a bloke I hadnt seen for years stopped to chat too, and almost fell out the window of his car trying to look at the bike ! I have posted a few pics of my day out in the sunshine, probably too many as usual. steven.
