hey guys i wana know wat is the difference between the lrp spec 1 .28 size engine and the spec 2 and 3

i am getting one and would like to know if its worth keeping and modding or just chuckin it on ebay....

its never ever seen a drop of fuel

and how long will it last before it blows up and is it reliable and easy to tune.....

i have a TTR pro 21 bx-r in my savage which i have ported myself on about the 25th litre and its still been goin strong for the past 30 litres since the porting and starts first pull every pull,has had some lean times and some times without an air filter lol

still goes strong like a battle tank and flips my savage onto its roof every slam of the trigger....and i mean with 40 series moabs and a wheelie bar with the biggest wheel on there and lowered about 1 inch ground clearance!

any help with the lrp will be much appreciated

The Lrp motors are picco based motors. I'm not sure which version though.

so wat are the differences?

only the Z12Rs are picco based, the .28s are Golden Lion/SH Based. i think the .21s are to

oh no last thing i want is a sh engine

Hi,

the Spec.3 has completely new timing for the inlet, exhaust ands transfers aswell as a new carburetor. 8+1 ports instead of 6+1 (Spec.2) and 3+1 (Spec.2).

The Spec.3 is available as Pullstart version or "Truggy" version. Truggy version features a normal backplate instead of the Pullstart and a thermal protected carburetor. You will need a starter box for the Truggy version though.

Best regards,
Andy
