Do It Yourself. Feeling game try some of the mods outlined in here. Some of these can be peformed by novices others require a substantial amount of knowledge before attempting them
then replace if you have some knowledge and are confident do them yourself its not very difficult just time consuming, you have be careful not to lose anything in the heads, and be willing swear your head off when doing the rear bank
Go to Repco & ask them for some oil flush products. Half the noisy GR lifters I have come across lately, I've been able to run a flush type product though a few times & they have gone quiet again.
The main issue is old oil baking onto the insides of the slide tips - flushing can get it out.
Hey thanks a lot for the info bennoz, i was looking to change mine some time soon. Do u know of any differences between kempy's aftermarket lifters and the genuine ones? nd where do i buy the mitsubishi lifters?

I found that while the Kempys lifters were good, their life expectancy wasn't as good as genuines... but, even if you have to change them twice, its still cheaper to buy 2 sets from Kempys than it is to buy genuine items from Mitsubishi.

The lifters control the valve clearance, the better you got that set, the better the motor will run. Also good to change worn ones because if you have one seize up, it can lead to total destruction of a head in the worst case scenario.
Yeah its a shame I never had a GPX to do a DIY guide on..
Anyways - there are also hydrulic lifters in a GPX that need replacing from time to time too. There are 12 of them, they are used to keep the mivec rocker arm on the mivec cam lobe when its not in use:
ohh i went on Kempys to buy the lifter just the other day nd
sent away the order form to get an email back 2day that the
price has gone up from $500 NZ for 24 to $600 NZ
