Has anyone here fitted the Moorespeed pistons? Have read related posts and Richie's website but am looking for info from a riders perspective. A quick (:eek:) ride on my favorite twisty road yesterday convinced me that I really enjoy the GSPD and so have shelved (for now) plans to buy a newer bike. Am coming to terms with the HEL front brake and it works well enough. For the type of twisty mountain roads around here the GSPD needs a bit more punch'(especially exiting uphill corners) and as recommended by others the Moorespeed pistons are probably the simplest & most effective way to go.

I envy the blokes I know who own one bike forever and never contemplate changing or modifying it :blast :D
 
Hello

BTW does any one have dino tests from other piston suppliers that we can use to compare with Moorespeed pistons?


could be interesting to see some numbers from 1070cc

thks
 
The Moorespeed pistons usp is in the shape of the crown giving increased compression, the 1070cc kit was one way to go,but involved a load of other work to the engine,but the biggest gains are with Richie's pistons. Plug and play, simple.
 
Remember Moorespeed bhp's are at the wheel, most quote at the crank to make the numbers bigger. reading the posts from the other site, they were singing the praises of Siebenrock,but Moorespeeds conversions put out loads more bhp, they were talking cobblers methinks.:augie

"Most" might be an exaggeration, but it reminds me about this one:

even jim cray only got 62.5 ft/lb with a1070 kit modified heads twin plugs and dellys and you are telling me you have 57ft/lb with your kit at the back wheel. are you sure the dyno hasnt callculated the losses and given you the crank hp and torque because from all the bikes i have run the losses are about 18% and as if by magic you take 18% off your results and you have about the same as wreford miles.

I look forward to see longtime reports on the Omega-pistons and I'm curious about how it works with low-octane fuel.
 
That guy on horizons unlimited was spouting some right old bollox, its a shame when folk slag off stuff without the full facts, only opinions. Oh well, free speech at work. I don't know about the Moorespeed pistons and low octane fuel,mine will run on 97/98 ron,but it is going to be pretty highly strung.However, Moorespeed engines are designed to do desert rallies,and there's no guarantee of decent fuel out in the middle of no where so I assume the Moorespeed set up will work with pool quality fuel. Why not email Moorespeed and ask?
 
Moorespeed/Omega pistons arrived yesterday. Almost too pretty to hide inside the motor. Awaiting the arrival of a gasket kit and then in they go :thumb Will let you know how they go.
 
hello

Please keep us informed after you assemble the pistons...

Especially about pinging with low quality fuel (and with 95 octane)

I want to decide with path to follow. :rob

Hi


Did you get the 18% tuning kit with the free flowing air filter mod to go with it?

No Pete just the pistons.
Tightarsedness kicked in :D I reckon I can fabricate a similar unit if required. I may do a short run on a damp day (less dust) with no air cleaner to see what the difference is. I have found that removing the original air box snorkels makes a noticeable difference to performance.

Cranky that Motobins didn't include the top end gasket kit that was supposed to come with the pistons or I'd have those shiny suckers fitted by now :( Should be sorted by the end of next week.
 
If you don't unscrew the two nuts that hold the head to the cylinder you can reuse the head-gaskets.

Just to make sure, but which way better or worse performance.

Richard Moore rekoned it was worth a couple of horse power with his pistons.

When I first saw the mod I was a bit concerned that the filter was too exposed compared to standard then read a few things about the mod done by different people that I hadn't considered before like: in dusty conditions the dust just lies on the conventional flat air filter - eventually blocking it up. With the vertical mod the dust falls off the sides of the filter due to the engine vibes, keeping the airways clear.

Better.
Lots of people doubt this but because it is so simple to do I would suggest that airhead owners should try it and see for themselves. Seems to be well documented that the airhead airbox is too restrictive.

I've tried it and with my bikes it made more noise, but my stopwatch told me it was not what I was looking for.
On the other hand Mr Moore has an airfilter with more volume on the clean side and I think that's the way to go.
 
The main difference I found with removing the snorkels is that the engine was crisper and more responsive. I agree that Richie's air cleaner is the way to go especially with the high comp pistons. To do the job properly I reckon you would need aircleaner, rejet carbs, omega pistons, some head work and a free breathing exhaust system. Then a dyno session to fine tune.
 
after a lot of dyno sessions with pistons on bikes with bing carbs when doing the airfilter mod the jetting needs to be changed up one on the main jet from 150 to 158 and then drop the needle one groove to lean out the mid range.
