Stedman58 Posted March 1, 2012 Share Posted March 1, 2012 Hi all, New member here - name is Steve, recently came into possession of 125 virago 2001 - motorcycling experience negligible - mechanical skills very basic but willing to learn, just a quick question if you don't mind ( probably the first of many dumb ones ) .The acceleration of the xv 125 seems a little sluggish so I was thinking of putting a new rear sprocket on with a couple more teeth would this improve it noticeably - I'm not too bothered about the max speed , if so would I need a new chain with how many more links ? cheers in advance Link to comment Share on other sites More sharing options...
2 Wheels Posted March 1, 2012 Share Posted March 1, 2012 Try 2 more teeth on the rear You might have enough space in the adjustment of the chain at the rear wheel,,,, therefor you might not need a new chain,,,, provided the chain is ok in the first place. By right when changing a chain you should change both sprockets at the same time Welcome to the YOC Have you introduced yourself ????????? Link to comment Share on other sites More sharing options...

Stedman58 Posted March 3, 2012 Author Share Posted March 3, 2012 have changed oil and filter - just a quick question, as I am replacing/cleaning etc different bits I am trying to replace the original philips type bolts with s/s allen bolts but on the oil filter cover the front bolt is a lot longer than the other two does anyone know where I can get an allen bolt that size,cheers. oh yeah and the rear spocket says 47 on it so I'm assuming that its the original sprocket not sure about front one ,I haven't taken the cover off yet - air filter and spark plugs next job so - ?'s will probably be following - The bike has only done about 4500 miles - and the people who sold it to me had it from new and they seem genuine so I've no reason to disbelieve them and it does look clean enough for that to be true, so I'm not sure wear and tear will be too bad-anyway like I said I will try the things neversaydie has suggested Link to comment Share on other sites More sharing options...
neversaydie Posted March 4, 2012 Share Posted March 4, 2012 I think original sprockets are 13 on the front and 47 on the rear. Dont get the bolts mixed up when re-fitting. One tip is to sketch the are youre working on a piece of cardboard, then push the screws/fasteners into the cardboard on the sketch, in the location that they fit on the bike. For your bolt, try yellow pages for a local bolt/fastener supplier Link to comment Share on other sites More sharing options...
Stedman58 Posted March 4, 2012 Author Share Posted March 4, 2012 Thanks for advice neversaydie - I'm pretty sure the originals were as you say so maybe a 49 on the rear and a new 13 on the front and a new chain and as 2 wheels says maybe I'll have enough adjustment on the rear wheel not to buy a longer chain eh? but I'll check the front sprocket thats on it before I start messing,cheers Steve Link to comment Share on other sites More sharing options...
