These pipe springs are good quality but I would personally recommend the o.e.m. springs for any application. I feel that these are a little to universal for my liking but are a great option for a set of spares in the tool box. on the other hand the o-rings are awesome, but please make sure you are running an FMF pipe as they are designed to be used with an FMF pipe.
Good quality product that serves its purpose well, have used these for many years
Excellent product, I would recommend it to everyone. The product came on time too.
to start off the springs were to short and the o rings did not fit properly the stock o ring is wide on my bike and this kit came with two smaller o rings.
kit fits perfect, simple to install! No more exhaust dribbles.
Bought this kit for a 2001 cr250 to replace my old worn out springs and my toasted exhaust O-rings. The springs fit beautifully, nice and tight, but when I installed the O-rings and slipped the pipe in, both O-rings ripped. Springs were great, but I'd go with oem for the exhaust O-rings.
Installed easy, works well, no more exhaust leak.
rings seemed kinda small. didn't really seal well and i was blowing smoke from the head after two rides
Your oem springs are much better. I bought this for new springs and read the reviews about some breaking. One of mine broke a few races in. Plus theyre a little longer than my oem yz springs and not as stiff. Orings are orings but dont expect much from these springs
5/5 on ease of installation ONLY if you have a spring removal/install tool (I have FMF's). Overall rating 4/5 because they are just o-rings. Durability/performance/power get a 3/5 only because I haven't tested against anything else and they WORK. I had old worn rings and replaced them with these and they sealed up and got rid of all smoke coming out between my cylinder and pipe.
Just rebuilt my 2000 YZ 125 motor, and purchased this kit to replace the old springs and seals since I have a fatty pipe and turbine core 2 silencer. During break in time with 15:1 fuel one of the brand new springs snapped off the pipe. It was running at 1/4 throttle for an hour in 3rd gear on flat ground. Seriously not happy with this kit from such a reputable company.
The springs are great but the o rings needed to be replaced after 5 hours. not very happy.
Fits perfect no complaints so far
Installed the springs using the FMF Spring Puller (Great tool) and the broke during my first moto at the track. The hook parts on the ends are the weak points. I found one spring dangling from my case with the opposite hook completely missing.
Fit perfectly on my Fatty, RM250
worked pretty good not as strong as i would have thought. The rings are a waste though.
it fits on my YZ250 with a fatty pipe very tight fit..works grate!
PURCHASED THIS KIT FOR MY SONS KAWASAKI KX 85. THE O RINGS FIT PERFECTLY BUT THE SPRINGS WERE TO SHORT SO I SAVED THEM FOR MY HONDA
I purchased for a 2004 RM250 but the springs were too short... they stretched out to the point of no return... also it only comes w/1 o-ring, its not the dual style like the pic. shows
I would recommend ordering the Honda OEM Seal and Springs.
You would need: Honda OEM #91304-KZ4-L11 (seal), Honda OEM #18332-KS7-830 (springs). You would want to order 1 seal and 2 springs.
