Pipe Specifications

[mrsquirrel]

I live out in Thailand and have a 400cc Dragstart 2003.

I've been looking into getting pipes made for it - but do I need to go for any specific dimensions at the back? Or do I just let them build them roughly - obviously to fit onto the manifold though.

Will I need to get any work done on the engine?

What is rejetting?

For all of you paying the pound for work to your bikes - A crash bar, sissy bar, rear passanger foot plates, hand made leather x - large saddle bags and a new rear tyre cost me 15000B which is about 200 quid all fitted.

Thanks for the advice in advance.

Re-jetting is the changing (up or down) of the jets in the carb.

If you play with the pipes,you will have to do some work on your carbs.

(Why do I get the feeling it's like "groundhog day"??? :eek:

you can have the pipes any size you like - but it would be best to have a bit of baffling (a washer welded inside the pipe with a large hole - so say a 1.5" pipe with a 1" hole washer inside at a rough guess...)

re-jetting is adjusting the amount of fuel that goes in - if you have special pipes made you will need to adjust this. do a search for dynojet and see if they do a kit for your bike.. the kit has a new needle in it, and new jets to put in the carb. you will then need to find a rolling road or 'dyno' to run the bike on to check that the fuelling is correct.

good luck..

Cheers for that

i highly doubt that there is a rolling road available to me in Thailand that is reliable.

I will look out for dynynojet carbs kit.

I don't think i legally have to haveany baffling here but if its for performance reasons ill stick a washer in

Cheers again.
