skov Posted April 5, 2009 Report Share Posted April 5, 2009 Hi all, My '99 315r is a little too fiesty for me - is there anything I can do to soften the power delivery a little? Cheers, John Quote Link to comment Share on other sites More sharing options...
tt5th Posted April 5, 2009 Report Share Posted April 5, 2009 Try changing the throttle from a 'fast action' one to a 'slow action' one. Throttles Link You could also gear it down a little depending on what setup you have at the moment. Try changing the front sprocket for a 9 tooth one if it's still on the standard 10T one.

nzralphy Posted April 6, 2009 Report Share Posted April 6, 2009 You could lower the compression by putting in an extra 1 or two base gaskets. It will soften the bottom end and somewhat tend to push the power peak further up the rev range. Quote Link to comment Share on other sites More sharing options...
skov Posted April 6, 2009 Author Report Share Posted April 6, 2009 Thanks Guys. I've ordered a slow action throttle, so I'll see if that helps for starters. Hopefully it'll turn up in time for the weekend! Does anyone know if it's possible to retard the timing a little? Cheers, John Quote Link to comment Share on other sites More sharing options...

rdchair Posted April 20, 2009 Report Share Posted April 20, 2009 Have you got the washer in the front pipe still? if not, put one back in! Quote Link to comment Share on other sites More sharing options...
skov Posted May 27, 2009 Author Report Share Posted May 27, 2009 Have you got the washer in the front pipe still? if not, put one back in! Just had the exhaust apart - I couldn't see any washers in there. But I also couldn't see any washers on the parts diagram!? Quote Link to comment Share on other sites More sharing options...
grahamjayzee Posted May 27, 2009 Report Share Posted May 27, 2009 Alright Dave, The washer will be a large one that effectively reduces the diameter of the pipe at the point it bolts to the head. Restricted mopeds have similar thing and it's usually a big washer with a big 'ole and fits between head and exhaust. Dave Quote Link to comment Share on other sites More sharing options...
