Anyone Running Lomas Pipes

[headcoats]

Maybe I have been spoilt by TSA pipes and running Lomas on other bike (still YPVS engine),finding midrange pretty flat and nothing happening till about 8 grand and then pulls well.

Any dynographs of these in action or anyone else running some

I have Jim Lomas pipes on my 250LC. I purchased them via eBay and they were stated to be suitable for a 250LC. I subsequently found out that Jim Lomas does not make a suitable exhaust system for a 250LC, only the 350LC, same system.

Having written the above I have no problems with these pipes at all and certainly no mid-range problems. My bike was originally used for long-distance production racing, so it was not stock. When I converted it back to full stock road trim, and after a complete nuts and bolts rebuild, I used whatever the stock settings were to be used via the internet as a reference. I have never had a problem with these pipes at all, which, in hindsight, surprises me as they were not made to be used on a 250LC.

I use a pattern throttle cable which does not allow the setting up of the oil pump perfectly, it runs a little rich on oil, but beyond that, it seems fine and is as good as when I ran it on a previous rebuild with stock exhausts and the correct oil pump setup using a genuine throttle cable assembly.

Possibly jetting or a dyno run could sort your bike? are you running a totally stock setup? and I am not sure about this, but does Jim Lomas recommend jet changes if you fit his exhausts?

Not sure if this helps, but that is the only comment I can give!

As far as I know Lomas pipes are top end pipes

If they were that good we would not have needed Kenny 😁

The revelation of TSA pipes was getting an improved top end AND midrange

Need to put some more miles on the bores then see what it pulls too

Few more miles on bores and it definitely has a kick at 8 grand
I'm liking it now as it reminds me of the Athena barrels I had on ,obviously not as vicious.
Don't know if it's all down to the Lomas pipes
