Yamaha TRX850 Enthusiasts Forum

Hello,

I've introduced myself and now I feel bold enough to ask a few newbie questions

I have done a bit of searching for various things but can't find everything

I'm fitting a Dynajet kit with K&N filter and Iridium plugs - the fuel height according to haynes is 15.8 to 16.8 - is this still correct for the dynajet kit Nothing in the dynajet info to say that you have to alter this or check it.

Carb balancing -
Was going to use this - figure it should be ok - any thoughts, experiences


Cheers Bill

I used one of those to make engine slider protectors and wasn't the missus pissed off , she had to buy another cutting board

I've used one of these things on the chopping board where the feck did you dig that up from! - i thought they were virtually extinct!

Difficulty is using it at low revs on a single cylinder - loads of fluctuations

Hello,

I had two of them, sold one to a guy on the RD forum, kinda figured that they would be alright on CV carbs - used to use them on Strombergs and SU's.

Used it alot on the 500 - works a treat and after a while fiddling about you get the hang of it

As to where I got them , I used to teach Engineering at the local college and I freed them from the Motor vechile section - They fetch a fair few bob on the Fleabay.

hopefully this weekend I'll sort out the fuel height and get the bike going again

Hello,

Well I got her going and I must admit that the fuel height setting is bl**dy hard to do - I'm pretty pleased with the end result., but I might make something up at work to see If I can do a more precise job.

Anyway I came to start her up and at first she wouldn't go

Turned over ok and before long it seemed that she was flooding- checked the plugs for a spark all ok (that's a pig of a job as well)

Fiddled about and then I looked in the manual and I decided to reset the throttle postion sensor- got the hang of that ok and low and behold after I reset it she fired up straight away

Right so now to check the carb balance with super tool - no 2 cyl was nice and steady but No 1 was jumping about all -couldn't get a steady reading

Had a look and realised that the no2 cyl pipe was going to the fuel tap and no 1 was just floating about in the air. So I swapped them around and I could balance them

I'm going to borrow some vacuum guages of a mate and see how good or bad I've set it up.

That was the good part when I went to tighten the drain screw on no2 cyl she wouldn't seal - so it looks like I will have to take the carbs off again and sort that out

One step foward two back

By the way she seemed to run ok - but I didn't try her with the air filter on.

Cheers

I`m not certain I`ve fully understood all you`ve described in your last post masterbill but you might find this usefull:

That`s for the TRX,off FactoryPro`s site.

Hello,

Sorry If I confused you - I know what I mean

Anyway - the trouble I had was not with the float heights it was checking the Fuel height/ Level. Page 196 of the manual from the download section on here.

Cheers Bill

Ps . thanks for pointing out the factory pro site.
