starter motor

hi compresion engine is waisting my starter,have been offered a 2.0 kw one.
the man says, no need to change battery, this will realy turn the thing over .
is this right

[Phil]

compression releases. Cheaper.

Didn't I read somewhere recently about compression valves that are built into sparkplugs so that special fittings and machining is no longer necessary. Just a thought

[Phil]

They are available, but only for 14mm spark plug holes.

i,v got compression releses in there ,but iv got very high comp,if the bike dont start and i open the throttle a bit the starter realy strugles,should i get the bigger one .

[Phil]

You might want to consider changing the starter drive, ring gear ratio.
I would be willing to bet that you have a Hi4 ignition or similar. If so set it to `kick start` that will help.

it turns over so slow that it judders ,the new starter is £170 is it worth it for all the messing about.

[Phil]

I would say that if you have comp releases & a good battery it should turn over fine, you may have an alternate problem, it should not do that.
Just in case here is the info on the reduced gear starter drive set -up.

Would that help my standard 88 Evo 1340 Phil,it really struggles on the first throw,so i stop,then do it again and its ok.Bin like it ever since iv'e had it (7 years),starters bin cleaned etc + good wiring and earth ,new battery but it has made no difference,iv'e just learned to live with it ,and its never let me down (yet),must admit its a bit disconcerting sometimes tho.

This in in reply to your advice on Hi 4 ign and kick start setting

the thing is i cant get the bike to start ,but the moment i open the throtle, the starter realy slows down, why does it do this
