Hi guys,
Just picked up Yamaha SR250 with 16000km on the clock, was part of someones collection and stood for quite some time im assuming due to the low mileage and the great condition it is in. All the chrome bits are perfect, seat is perfect, engine is super clean still. Only the tank has a few scratches and dings and a few rust spots but nothing major.
My only concern, when I ride the bike, it kind of lags to gain speed as if its starved of fuel or air but once at higher rpm it pulls well again. I had a brainspark idea to remove the cover on the side of the airbox yesterday and rode it to work and back, approx. 50km round trip and it pulled so much better. I did check the air filter and its not blocked up or dirty. Its still pretty much brand new. So when I got home last night put the cover back on the air box and this morning it was back to struggling to gain speed until higher revs.
Could this be due to a blocked jet in the carb or maybe a too small jet in the carb?
I am planning on doing a street tracker build with this bike but looking to keep the stock airbox so that I don't need to make a new battery box or any major mods. Plan is to be able to put it back to stock if I wanted to. Will be buying longer rear shocks, mx bars, fabricating a new seat pan and changing the exhaust to a slightly louder one (this is for safety reasons, I stay in South Africa and people cant drive here so id like them to be able to hear me as the stock SR exhaust is very quiet). With that will come a few odds and ends that will be changed like mirrors, rear light and indicators.
Sorry for the novel LOL.
Thanks for any advice.
