Re: GSX-150 Misalignments Issue
As I understand it, the GSX-150 is intended to compete with Honda's GROM and is an entry level bike intended to be as cheap as possible. So they're cutting corners wherever they can get away with it. With that and it being new, build quality can suffer. With regard to the front stay, is it a metal piece and is it a welded assembly? If so you might be able to bend things to improve the alignment. The chain alignment is of greater concern, though I also wonder if it's something that they can get away with on a 19 HP bike. Normally the front and rear sprockets should be exactly aligned and there are various tools that can be attached to the sprockets to ensure that, i.e. to measure the misalignment. I think that there's a laser device for that but you can do better by attaching a straight edge to one sprocket and measuring the misalignment at the other. Off hand, yours looks like too much. But a pic can be misleading. You need to be more precise before calling out Suzuki on it. Possibly it can be fixed by, for example, using a front sprocket with an offset. However, as previously stated, this might be something that they can get away with.
I'm unaware of such a misalignment on my '95 XT225, which has similar power. If you can, you might try checking the alignment on other models, Suzuki and others, that are similarly priced.
