chrisedwards Posted July 8, 2012 Report Share Posted July 8, 2012 Would be very keen to know : 1: what do the 4RT community consider to be a good all round sprocket set up ? 2: It appears an S3 280 conversion kit is a straight "bolt on and ride" without having to do any extra machining work to cranks and cases etc. I am very tempted to buy one as I feel it may give extra talky power of the bottom , right or wrong ? I am an ageing expert that still likes to have a go but feel sometimes my 250 is a bit weak when pulling a higher gear from short approaches. Lowering the gearing , i.e.: 43 on the rear made it manageable in technical areas but I felt all gears were to short. My bike currently has a mitani clutch and exhaust system and I am lead to believe is running a Sans setting. Rear sprocket is a 41. Look forward to hearing experienced views on these subjects Chris Quote Link to comment Share on other sites More sharing options...
jimmyl Posted July 8, 2012 Report Share Posted July 8, 2012 I found the 280 kit a handfull and changed back to std 250 on the 09 I bought, Had sains map on at the time. Currently running a softer version of the sains map, Have rdden the clubman route with some success on a few of the S3 rounds including colmore and found the 250 was stilll getting me out of the big climbs as good as anything no problem . I run std gearing (10 41?) and ride lots in bottom gear and use the rev band to get what I need top end. 4rt does not like to be revved and then dump the clutch like a 2 stroke. Have found ride off the throttle and then give it lots once the drive has hooked up, I find 250 does this where the 280 was spinning or just dragging me behind. As you have a PTB would suggest probably best playing with alternative maps which costs nowt before spending money on a 280 kit. Youll probably want to play with maps if you do fit a 280 kit so may as well do first as last. Best of luck Quote Link to comment Share on other sites More sharing options...

apj Posted July 8, 2012 Report Share Posted July 8, 2012 I run 9 on the front and 43 on the rear and find this ideal for myself. There are quite a few 4RT's in our area and most seem to run this combination, but a 9 and 42 might be worth trying. Quote Link to comment Share on other sites More sharing options...
