gn400

[guest1680]

I have 80 gn400 I don't know a lot about it first bike one thing is that it back fires when I turn it off. I want to know how I can fix that and where I can find parts for if aftermarket or stock

[Smithy]

When you say it backfires does it just pop once or does it give a series of backfires? How well does it run when it is running?

As for parts I find that ebay is probably the best place although Wemoto will have brake pads etc. What are you looking for?

When I turn the bike off it back fires I think I need to play with the carb and I am looking bobber part like lowering  for exhaust  and

backfires are usually where the bike is sucking air into the exhaust system. Check for leaks first off.

As for parts Wimoto are OK, but older suzuki parts are sometimes cheaper from Crooks Suzuki. Nice guys and helpful too.

Hope that's a help.

Seems odd that it only does it when its turned off. Does it smell hot when you ride it ?.

gn has an odd magneto type self generating ignition, do you turn it off with the killswitch or the ignition key?

[guest1680]

it back fires one after i turn the key to off. i just found the header bolts backed out alittle bit. all the looking around there not alot of aftermarket parts. i will have to make alot of my parts the i need when i do my bobber. but it will be fun. i have aother ?  i dont know a whole lot about carbs but when it is stting  after i have rode it gas leaks out of the bottom look like it is like the overflow hose

[johnr]

if it fires when you turn the key off it must be sparking, asi said the gn has a magneto type of self generating ignition, does the bike have a kill switch? if so when you stop the bike with the kill switch does it subsequently fire when you turn the key?

[guest1680]

I don't know I have not done it that way I will try it that way and see what happens I did find my header bolt were loose so I tighten them up and now it is raining

[steveD]

Hey Mike, do you recon if you loosen the bolts it will stop raining! (just a thought)

Hi Mike

I started out making a GN400 bobber but as I am the messiest worker in the world it became a rat bike instead. I've made all the little brackets and spacers myself which has been really satisfying.

What parts are you looking for?
