TTR600RE Carbs - jet type/code advice

[Pigford]

I need to get some different jets for me carbs, and ideally need to know which types they are?

Heres a link to Allens who stock loads of stuff, but don't have any details of what the jets are. Anyone pick out which they are from the list......

Allens Performance Mikuni & Keihin Carbs

I have fitted a 165 main in the primary ( N100604 ) and not touched the secondary carb yet. The thread was a bit snug though

I was after a 155 & 160 (165 is too rich) for the primary, and a 150 & 155 for the secondary. Looking at the manual, they look to be different types of jets in each side :confused1:

[Pigford]

Right then (even if nobody is interested) I have sourced some jets....

The primary mains are easy enuff, and about £7 each.

The secondary carb is a bit trickier, coz Yamaha don't do anything bigger than the standard 145 Now I could but anuvver std jet (£12 ) and run a drill thru it, but thats gonna be a bit hit & miss.

These jets are a strange size, as they seem to have a large thread.

The bike does run reasonably OK at the moment, but it is a bit "fluffy" on initial throttle (bit rich), so if I try a 155, I really would like to go up at least to a 150 on the secondary to make sure its rich enuff on larger throttle openings.

Allens can match jets, but need to know the spec of it .... which means taking it out & checking it, then ordering one.... but the bike will be off the road - and its Xmas

hi piggy liked the pics of your rear shock fitting, my old pipe looks good maybe this site www.off-the-road.de has info on jets and setting up lots of other very nice parts for our bikes anyway thanks steve

Hi Steve - thanx for the link buddy..... All the best.....

Iv heard of people drilling out the secondary and taping threads to fit a standard mikuni jet. Jets would probably work out alot cheaper too.

[Pigford]

Could be an option......

The secondary main jet appears to be a rather large thread.... and access from underneath is via a long narrow tube, which is a bit of a struggle

As its a bit cold out in the garage, I can't be arsed to take the carbs off and have a fight with cold/hard rubber manifolds.... so gonna leave it for a bit now....

Cheers for the input tho chaps...
