hi scotty. the barrel can be modded to 270 and the hot mod was to shorten reed block. also good idea to remove wieght from outside of flywheel. i also made brackets to lower footrests and converted rear wheel to tubeless with disc brake useing old style gasser wheel. still have a few ty parts alloy kickstart gearlever bigger air box etc and gasser wheels if interested

any more info on converting the back wheel to tubeless?

I have TY350 (several) and converted front to a GG disc brake 4 piston, works great. sort of like your pinky I guess.

I'd likd to convert the back. Drum brake is fine, but I'd like to get away from fighting tube repairs.

I have a 2000 GG rear wheel and brake, same source as the front.

With the lowered pegs, how did you mount a master cylinder and rig up the linkage to pedal?

I assume mounting the wheel and caliper is the easy part. Did you float the caliper on a bracket about the axle, or fasten to the swing arm?

it's a 'someday' project, but looking for ideas.

tks,

I found this website a while a go for TY350s, my plan was to adapt the mods on there for my 88 TY250R, but I haven't got round to it yet.

Has anyone here done the footpeg mod by moving the whole bracket down the frame tube?? I reckon the pegs want to be about an inch and half lower ?? Any other trick mods for the TY mono ??

The popular mod of the period was to increase capacity to approx 264cc using a Yam IT 250 piston,shorten the inlet tract,can't remember how much and also cut away some of the reed valve petal.I cant remember if any porting work was involved- probably was.I had various tail pipes on mine,ranging from one of Shirty's to a Kato,then a WES "GO" and finished up making my own.I had a spare back wheel with a Talon hub like quite a few people.There must be a few still about.There were various aftermarket carbs on the market at the time all reputed to improve performance.There were some good riders on Yam monos at one time,Scarlett,Alderson,Birkett,Andrews etc.Probably the most exciting rider I saw was young David Page.He was destined to be very good but sadly his premature death ,from I beleive leukaemia,meant this was'nt to be.

ALT.

Yes the dreaded 270 conversion there are good uns and bad uns. I had a bad un like a moto crosser. If you have a good un they reckon they are great. Sold mine sharpish, got a 250 pre pinky mono to ride now white framed one, going to lower the pegs etc.

ask a guy called "Steady Lejeune" , he is the TY Guru in the Northern Centre.......

He whips my Sherco "week in week out" and he's on DRUM BRAKES........

A good rider on an old bike beats a young rider on a new bike.........

They're the best ones them!
