gearing up the suzuki gt250

[dollydog]

while i've been building this monoshock and reed valve gt250 i've come across alsorts of sprocket sizes while i've been looking for the correct ones for this. anyway, to gear up a gt250 and use a lighter [520] chain, use a 39 tooth sprocket from a ts185, you need the one with 12 bolt holes in it, 6 x 8mm and 6 x 10mm. then get a 15 tooth front sprocket from a suzuki rm465 and ratio is down to 2.6 from 2.93. bit slower on acceleration, but quicker on the top end. in case anybody's interested. yes, they fit perfectly

Hi DD

Good info thanks. This mono-reed 250 project must have passed me by. Got any pics?

Cheers

I wonder how you know that then?

for once i agree with him
trawl being the operative word. at the last look it was 31 pages long - most of that is the engine. did i mention it was also now a monoshock? i love trying different things - and upsetting the purists
cheers, dd.
