14 tooth front sprocket on curvy

[Quiff Wichard]

well I have done it!! curvy 02. - well you ALL know my bike

yes I know I should go up on the back and get a longer chain.. and save on chain wear and petrol..
but, wanted to see if I liked it first for a tenner !.. then if I do. I can get the whole new set and sell my new front sprocket on .


so- results?

I LIKE IT !!!!!!


I only had a quick blast. but wow the acceleration was awesome- felt like a different bike.. ..

cant say anything about top end or motoway iding or wheelies cos aint done any of those yet. but will report back on the above- especially the petrol useage (miles to a tank) and if I am bouncing off the red line all the time..


first feelings though are I am going to like it..

bit scary .. doing it myself- riding it knowing it was ME who put the back wheel back on and the chain etc.. but then I knwo I did it right and double checked everything.. so I should relax..

it was only a half hour job,, and 15 of that were borrowing have right tools off my neighbour.. didnt have a big enough socket for the sprocket or the back wheel nut!! must buy some

so what size are they?.. anyone know.. and cost?..

removal etc and replacememt were simple.. mainly due to info on here.(thank you Mr Vine ) from an old thread.. must say though the sprocket nut didnt even seem tight . came undone simple..

so its all back together and I am chuffed..
looking forward to a long ride and ssome difeerent roads and letting you all know how it is.. at this juncture though - it put a smile on my face so Iam happy..


couple of Q's??

will the engine get hotter quicker now?
will it wear my chain real real fast or take ages?
and is it correct its better to go bigger on the back and longer chain ?

thanks..

22mm rear axle nut, 17mm for the bolt on other side. the sprocket nut i think is 28?? MABYE 32. i go by looks on larger sized sockets.
what size rear sprocket are you running?? i have yet to take the bike out with the 14 tooth on front. got a 47 on the rear so will be interesting.

cheers for the info-

standard sprocket on the back

standard for an S .

why did you take the back wheel off?

& i will wait till u do some motorways b4 i decide

[Quiff Wichard]

I dont do motorway-
only time I will is up to the norf south and to the AR ..
but I can blast down a local dual carrigeway..

I didnt remove the wheel.. just slackened it off to enable the chain to pop off the sprocket.. and then to adjust to the correct tension afterwards.. ,,,

please let me know what it feels like at 120ish

^ ditto that.

and is it correct its better to go bigger on the back and longer chain ? Going down on the front sprocket means you have less room for adjustment of the chain. It also puts less stress on the chain (apparently), if you change the back sprocket & not the front.

thanks..

All, IMO Only.

Also, a pointy rear axl has a 24mm nut on it. Or at least mine has...

so...............

all is good

did not notice the 10mph loss speedo showed 130 which is the most i had with the 15

100mph @ 8000rpm

did not do motorways just a few short duel carrige ways i was woorried about the engine over reving, but did not find a problem

i am happy as larry
