Just checked the Valves on a 1994 with 61k miles and I am pissed...

Ok. So I was really pissed after I finished checking the rear cyl valves and found all of them where within +/- .01mm of spec because I felt like I just wasted my time bothering with it lol. The previous owner never had the valves checked. this was the first time the valve cover came off since factory.

After debating whether I should bother checking the front I said what the hell and did it and found front right intake valves at 0.12mm and all others in spec. I adjusted that and buttoned her up. I don't think I will bother with the valves on my 4th gens for another 70k miles.

When I checked valves on my other 1994( the daily ride) few months ago it needed two sets of valves adjusted at 55k miles. But that bike has seen some track time and the ridden pretty hard all around.

I checked the valves on the 1996 when I got it at 16k miles and all where in spec but I remeber two of them were near the tight limit. I am going to check that bike again after I finish with the current projects at hand and then for get about the valve checks till it crosses 100k.

I thought I would throw this info out there data points. It seems the valve wear a little when breaking in and then stays at that clearance for a long time on the VFRs. My conclusion is that checking and adjusting them once before 50k is important and then they can be forgotten about for next 100k miles unless they bike is constantly ridden hard.

 

Yep, I don't plan on ever checking mine. Now, mine is a vtec, so there's a little more involved in the procedure. After the many vfrs I've heard about going 50-100k miles without adjustments I'm not really too concerned.

 

I will check mine when it turn 90k which is soooon

 

Yeh mine were done at 30,000 (within spec) and again at around 70,000 clams, again, all within spec. Its easier to do than some bikes actually, I dont know why people in the business bitch aboot getting the valve covers off and shit. AnywHoo-Gona take it oot very soon and heat up my oil and burn some petrol off...:thumbsup:

 

The VFR is one of the easier bikes to do the valve adjustment simply due to the ample space and lack of timing chain and tensioner. It was more time consuming and harder when I adjusted the valves on a f4i and cbr 600rr. The f4i was done at 30k miles and 9 valves needed shims. The 600rr was done at 15k miles and luckily all of them where in spec. The f4i was especially frustrating due to the location of the CCT.

 

FRI had a nice aluminum frame but that was aboot it! I hated working on those bikes as they had one entire cam cap and if you needed to change a shim, that meant you had to remove the entire deal.

Add insult to injury, they vibrated my balls ound: Love my VFR btw, but you knew that, she is my "FIRST WIFE." My bike has gear drive cams, so no CCT...:tongue: I am a snob :lol:

Missus hates hearing that, wish Stevie Ray Vaughan had a guitar sticker that sed that...:rockband: :drummer: :guitar: :thumbsup:
