Hi all. Glad to be back. I was told not to ride motorbikes again by my doc. Since I broke foot its fixed my left shoulder for some reason so on Tuesday went out and bought a 1987 xt600 2n4 . Love to be back on a bike again. Now where do those restrictors live?

Great news Simon

Good on yeh si",   you still on the DT "   forum too ,, ?  ,

Yes on dt forum. Not ridden it in a while. Trying to log in here on tapatalk to upload photos of the pair but its not accepting password. 

Love the kickstart only on this 1987 minter. Whilst learning the technique a hot start took me 10 mins. T shirt soaked in sweat. Youve got one try. If you flood it its over. Move away from the petrol pump so other people can fill up. 

Yeah we've all got a bit soft with out leccy starts, certainly a challenge klckong a 600 single

Speak for yourself, none of mine start with a button, (I can say that cos the Hondas lazy button don't work). 

Anybody know where I can get an airfilter guide that fits between upper and lower airfilters. Its missing and unavailable so my airfilter gets sucked into the carb. or will I have to fork out for a K and N?

Here he is

 

 

Looks awesome, sounds mint too 

Cheers finnerz. No knocks or smoke.  The bolted on tailpipe ia off a rz250. Might sell it when I buy another tailpipe. Maybe it was part of the 20kW restrictions. Bit rhe bullet and Ordered the k&n. Arriving tomorrow   60 quid. 

I thought the pipe looked a bit strange lol. How else is it restricted?

Still trying to find this one out. Will have To go through full cmsl parts list to see if cdi is restricted. Apparently its a rare model. 

Just quessing here but seeing as the 'normal' XT uses a dual stage 27mm tekai carb, I would think your bike with it having a whopping great chunk of hp cut, like 15 or 20 kw. That the easiest way to neutralise the power would be to use a single carb, or de activate the second stage.

That is an awful lot of power to lose from a cdi, all that can really to is change the ig some and clip peak rpm, neither really restrict a big single. So that's unlikely. For a really small market model in 1987 Yamaha would not have bothered themselves with developing a different engine/cylinder head.

But stopping the second stage (just like blanking a powervalve on a 2 stroke) and some exhaust/inlet  restrictors would be really easy.

I may be miles off, but its where I would start.

 

Ive got to investigate but I have read on the interweb that the carb rubbers maybe different. The exhaust headers look quite thin too. Another investigation to get my teeth into. Woohoo

Hee" i think it sounds ;ile one of them static engines " [ same bhp too,   . ----  then am a  biast   2stroker,,, 

 

Oh thank you so much blackhat. I wish the idle speed on the xt went that low. 

Do you want a 0-60 race on my 175mx?

I have the spanners out fettling stuff now. The missus is still at work 

Now the k&n parcel has arrived. Where do I apply the lube? 

 

Oh its put on the airfilter
