Re: Starter Valve adjustment location?

I am planning on adjusting my starter valves tomorrow and just wanted to make sure I have the right locations for adjustments and the 5-way valve (see attached).
I also am unsure of the location of the PAIR valve hoses to be unplugged and capped. Are they under the front of the airbox or at the rear?
Can they be squeezed shut without removing the airbox?

Thanks.

Re: Starter Valve adjustment location?

Looks like you have things correctly identified. *The PAIR valve hoses are the 2 larger (~1' outer dia.) hoses that exit the top of the valve cover, so under the front of the airbox.

If you have some proper hose pinch-pliers, and they are long enough, you should be able to get at them from the side fairing openings. *I was able to reach mine from both sides, but had to get my son to reach the left side hose for me, as my hands were too big to stuff in there. *YMMV, as I believe you are on a 929 and I'm not sure if the access is the same as 954.

Good luck with it; like others have reported, I found that doing the sync on my throttle bodies just smoothed-out the idle a bit and also the off-idle throttle response.

Re: Starter Valve adjustment location?

Thanks for the reply. I have a 954 and not a 929, so your advice should be particularly useful. I have a surging/hunting problem at 3,500 rpm and believe adjusting the starter valves will help things out. If this doesn't help, then I will see if the previous owner disconnected anything and hook it back up. I have heard that the flapper valve being disconnected can cause this problem. I think this is the valve for the exhaust?

Re: Starter Valve adjustment location?

I think I was referring to the PAIR valves. Anyway, they are hooked up and so is the flapper in the airbox. The starter valves were not too close together, so I got them sorted out. The surge is better, but still not gone. I reloaded the Erion slipon and stock air filter map and the low end hesitation is gone, but the surge is still worse than with the stock map loaded. I will just have to get use to it unless someone has had the same problem and cares to share their solution. I have a 2004 954 with Erion slipon, stock air filter, O2 eliminator, and PCIIIr. Has any one with the equipment I have installed, tried a different map (other than Erion map) with success? Thanks in advance.

Re: Starter Valve adjustment location?

If your done with the mods, perhaps try having L&L do a custom map for you? He's up at WSIR at least once a month.

Re: Starter Valve adjustment location?

Just an update, I loaded an ARATA California map this morning and the low end pause is gone and the 3,500 surge is also non-existant. It appears to be running a little rich though. This tells me a good map is out there somewhere, I just need to find it or pay for a custom one. More to come.

I will be at Willow Springs Toyota 200 this Sunday, so maybe he will be there and I can check things out. Thanks.

Re: Starter Valve adjustment location?

I had the same surging thing happening with my 929, I've got a custom map done but he didn't really pay much attention to anything below 4000, which is where all the surging comes from.

I found that by just messing with the map at the appropriate rpms it can be smoothed out, try to move the smooth part of the revs downwards 500rpm at a time -ie if it starts to bog and surge below 3500 then work with the 3000rpm row first and get that right and so on and so on.

leaning the mixture out about 5 to 10 worked for me, it' s still not perfect but I was using my mates laptop and it's quite a slow process, load changed map, unplug laptop, put on helmet go out for a test ride, come back in, do it all again.

I thing the starter valve sync, throttle cable adjustment, and chain tension all play a part in the surginess of the bike anyway, mine haven't been looked at for a while so will set them all correctly before I tinker with the PCIII.

Cheers
Ben.

Re: Starter Valve adjustment location?

Thanks for the advice. The Arata map seems to be working just fine, and I got 37mpg when I checked this morning. 1/2 freeway riding, and 1/2 twisties after work (semi WFO). There is still an occasional surge at the 3,500rpm range, but is manageable now.
