Hi , i know i shouldn't do this, but i did none-handed on the bike and it seems to pull/fall to the left slightly is this because of the swinging arm and exhaust or frame damage, doesn't pull while one hand or two hands on it, just curious, perfect handling in normal riding conditions. must stress i don't ride none-handed all the time, previous bike had an under-seat exhaust so maybe this is a factor. Thanks , just trying to see if there is hidden frame damage

Road camber might be having an affect.

no its more noticeable than that, if i shift my bum about 5cm to the right it is balanced

can you lift the front wheel and spin it? might be dodgy wheel bearing?
Are the forks the same distance through the yolks?

Rear wheel alignment.

forks same distance, i thought it might have something to do with the swinging arm and exhaust being to one side, i am a light person as well so maybe more noticeable, maybe im not balanced lol

Has the bike ever been in a crash that may have damaged the frame?
Are there any signs of crash damage to footpegs, exhaust radiators, handlebars and so on?

when i built my project exon valdez, it pulled to the left and was slightly out when i took it for MOT.
turned out the yolks were slightly pissed after a bump they once had. swopped them out and it was perfect.
similar symtoms as you describe but bear in mind all the V4's feel slightly left orientated due to the pipe on the side and extra weight.

i was thinking that, the entire bike has no marks on it, so no evidence of low side, i think its probably the exhaust being to one side and its stock so will have more of an weight impact, but again thanks for the speedy response

which way do your balls hang??
