How stressful are aggressive cams on an engine? Assume the head has moldstar 90 seats and bronze valve guides, or even stiffer valve springs if suggested by the cam manufacturer. Del West valves are also almost a no brainer as OEMs aren't too much cheaper. ... more »

All stock before teardown, I plan on going with a Vortex from TD but I'm getting the valve seats cut from PC so I figured what the hell let's do their head mods while we're at it you know?

Can anyone explain what PC head mods feel like? Or head mods in general? I've read/heard that sometimes they feel on/off. I'm looking at Twisted and PC since both of those shops have a lot of r&d on my bikes. Yes I don't need more power (if it gains ... more »

Thanks guys I replaced all 4 valves along with springs and it eliminated the smoke. Problem fixed

Added reply in a thread Oil on top of piston 12/31/2020 6:30 PM

Yes I did, according to my kawasaki manual. I think the problem here would be the valves being bent from hitting the piston or maybe even the valve guides from the impact the piston and valve made..I got some work ahead of me

Yikes I guess ill have to do a measurement on everything that could've seen damage.

Yes that's what I imagined. I did not check the cylinder diameters or ring gaps. I built this bike back together without doing the shit I always normally do. SMH. I also suspect and hope its the valves because when I first fired her up I don't remember ... more »

My recently rebuilt kx450f blows a lot of white/gray smoke. I removed the spark plug and i see oil on top of the piston. I do know that timing was set wrong on it and the exhaust valves hit the piston for about 45 seconds. Also noteworthy when i spun ... more »

WAIT just wanna make sure I'm understanding this right...your company makes all the colored end caps for the race teams.. AND they might be offered to the public next year??

I just posted a question on legacy carbon which I'll now delete. Same thing I ordered a 2nd green end cap because I slightly damaged my 1st during install. (I'm picky like this) so I ordered another one. That was in early September and still no reply. ... more »

I purchased an rmz 250 a few months back and to my surprise had everything from pro circuit that you can buy down to the valves. I'm concerned of the wear on the camshafts and if I can apply the service manual specs to test for journal wear even tho

I don't know of any shops/tuners that change settings on the GET. They have base settings for a stock piston and racing exhaust and pump or race fuel. Their settings can be changed thru the app but I'm afraid I'd butcher things and make it worse. How ... more »
