ttr600e jetting
After putting a DNA air filter in and a QUILL aftermarket exhaust can on the bike pops and farts on the overun...

I have searched the web and no one does a kit that is a 'fit and forget' system.I dont want to pay £70 plus for a kit that i then have to 'adjust' with different jets etc.

So my question is has anyone had a similar problem and can offer any advice?

When I first put an after market silencer on it did what yours is doing I think but it was blowing at the joint a bit so put some exhaust sealant on the joint and it was OK after. Yours maybe a different problem dunno.

Done that ...twice.Even sprayed soapy water on all the joints to check for air leaks..all good.Gonna try adjusting the mixture screw after advice from QUILL. was thinking maybe changing the jets would give some kinda performance gains..

A tweak of the mixture screw should help, although i had a gforce can on my old ttr and it was muchos noisy on the overrun, often with foot long flames banging out of the can, but the mixture was bang on. Was worth it for the extra grunt tho, made a big difference over standard can.
Been looking for a can, will try quill, thank you for the heads up

Maybe..
Hi, I have a TTR 600 which has a high flow air filter fitted and a Remus exhaust. It had appropriate jetting and ran well. I have a replacement carb with the normal jetting and it seems to run the same as before. I phoned Dave Lambeth about the jets to match air filter and exhaust and he said,"Who says high flow? They make next to no difference. There's a lot of shit talked about jetting. It would take me a day with the bike on a dyno. Just run it as it is." My bike pops and barks on over run but I've been assured they all do that. The Remus is ridiculously loud so the popping seems to suit the bike anyway. Lindsay.

Thanks for the response. I've actually trawlled through all the 20 odd pages of ttr posts and done loadsa internet searching,hasselling various jet kit manufacturers.

I just wanted to get the best i could/can outa the bike is all. Gonna worlk out which is the air mixture screw and back it out 1/2 turn first..unless its 'in' to richen the mixture...time will tell

If you have a lot of popping on decel, you either have an exhaust leak, or youre are running slightly lean on the idle jet/Co screw (fuel screw)

On my xt600e, I needed to go up on the idlejet, after fitting oversized headers, laser produro exhaust, and the top of the airbox removed, together with using a pipercross foamfilter.

The stock needleposition and mainjets were fine, actually the stock mainjets was still ever so slightly rich.

The Co/fuel-screw is just that, a fuelscrew. The more you loosens it, the more fuel it will flow, up to around 3 turns out, after that it cant open for more fuel, and you need to go up in the idlejet, turn in the screw, and start to loosen it again. You loosen it untill you have the strongest idle on a warm engine, after that you tighten it 1/4 turn. (rule of thumb)

Hope you can use some of the above.

I have a different carb now, but back then I went from a #46 idlejet to a #50, but I #48 would probably have been enough. I left the needels alone, and actually went down one size in mainjet on the primary carb.

Theese aircooled bikes come fairly rich stock, eventhough you often hear otherwise. I had mine on a dyno to be sure.

Heres the graph, stock bike with opened airbox, pipercross airfilter, and the tip of the exhaust removed, still slighty rich overall:

I would just go up one on the idlejet and call it a day.

Again thanks. Slight confusion though..in an earlier post you suggested lowering the needle jets by one clip...is that from the pointy end up or blunt end down?..technical language i know

Dont think I suggested that. Just change the idlejet, and leave everything else stock. And take things from there.
