Had ours fired up for a week or so - nice and warm:thumbup:

Thought "Pukka" made pies:confused1:

Just reported it, there are some pretty stupid people out there that will bid on such things but there again WE know what these saws should look like!
-
Glad it worked out OK, s big job and it looks like you have learnt a bit!

I have used the company and the ebay shop, no issues at all, very fast service. I had a major problem with a cylinder kit I got from him on the bay and he refunded my money straight away - not too many would do that so he seems like a good guy and willing to do the right thing. I will be using his products again!

Don't know how legal it is but any wood that comes down in the lanes round here, ends up thrown in the ditch and no one has complained about me chopping it up and taking it home - even the local land owner thanked me and pointed to some more I could have. The rules I use are don't trespass, if it is damn obvious whose wood it is, ask for permisssion and always clear up behind you! Oh...and if it has been stacked up neatly - it is someone elses property!!! I have had decent amonts by asking at local farms, the rest is dragged out of local ditches:thumbup: Just don't take the piss!

If you used an aftermarket cylinder, it is probably the quality of the part to blame:thumbdown:

Looks real to me........real poop:lol:

Try adjusting the coil to flywheel gap - I usually use a typical business card between the coil and magnets, loosen the coil bolts so the coil sticks to the magnet THROUGH the card and do it back up again.

Modern 125cc kart engines are limited to around 16,000rpm, the latest bike engines pre the the two stroke ban in racing were around 21,000rpm. The chainsaw engine will be pretty basic compared to the modern two stroke racing engine, modern racing or even road going two strokes will have powervalves able to pull 30bhp+ from a 125cc engine compared to 8-9bhp from a saw which hasn't got boost ports or powervalves!

Nice job Martin

Well I think you have been told a load of , Some of the fasstest ever racing small bore two strokes got up to around this level and to do so would have matched expansion pipes and porting - if this doesn't happen, the expansion won't have the correct effect.These racing bikes would have a very short stroke to get this sort of RPM and a bog standard chainsaw engine doing it..........under load:confused1: I would imagine these fellas took their standard engine, gave the data to a pipe specialist, matched the pipe as best they could and bingo - more power but to get to 21,000 rpm, you would need to start with a blank piece of paper and not a design for a saw that normally revs to 12500rpm or so. I will ask the guy who built it in April 15 when I am at the NEC again!
-
Where did the 21,000 rpm come from? seems damn high to me as even race tuned 125cc GP bikes don't get that high and these saws are not tuned to the pipes? From what I know, the saws never had the adjustable H screw carbs and when I spoke to the guy that assembled it, he hadn't done any engine mods to the saws!
-
It sounds like fuel starvation, wind out the L screw 2-3 turns and try it again, if it won't fire, try it on a single pull on choke and then back on fast idle again. Make sure the thing hasn't got fuel in the bottom of the crankcase by removing he plug and pulling it over upside down like I said before. If it still won't go, hold the throttle fully open with your right hand and pull it over with your left - no choke!

I did Stubbys 390XP and MattyFs 395XP at the same time and ran both of them together, the 395XP was faster but both have much that can be done. The vid is on Youtube [ame] [/ame][ame] [/ame] I am sure they will say what they reckon on them:thumbup:

He had tha saw imported from one of the porters Stateside, they seem pretty common there!
-
Now that would kick a little:lol:

Nice, Wes is like a pig in piggy poo:lol:

Generally the bottom ends are the last thing to blow - most real old saws I have seen have intact bottom ends with nice tight bearings and it is the top ends that suffer. I haven't seen any bottom end detonation on any of the saws I have ported and usually tune them to around 500rpm below max revs so it is probably just an unlucky fault. Significantly advancing the ignition could cause issues with the ends - having heard a saw with the ignition too advanced - it sounds a little bit like a bomb ready to blow! Was the ignition timing changed??
-
Yup, quite agree, the coil alligns with the flywheel at around 15 -20 deg, same as a 026 but it may be firing at 15 deg instead of 30 deg so retarded by 15 deg. There is no decomp on it and it isn't ripping the starter handle out of my hands like I would expect running 170psi on a pop up unbedded piston! Just needs a bit more tlc! Good luck with the new baby!
-
Well, I have tried out my ported 066 "Red eye" and .........what a dissapointment, very boggy in the cut and about as much go as an unported 60cc saw. I am thinking the ignition advance isn't right as this is the area where I had to set the flywheel manually and not with the conventional key. The next stage is to fire the saw up and use a timing light on it to see exactly what the ignition timing is - 27.5 - 32.5 deg at 8,000 is what it should be. Watch this space!
-
Just pulled a clean 395XP apart, it has been lightly seized so the bore has been cleaned up, piston on order and will investigate the reason for failure on rebuild. Also started on a MS200T that has a poor pickup, compression is a healthy 180psi and suspect carb issues but am giving it a full strip, service and porting/muffler mod. Will be good once done:thumbup:

395 chain going slack then tightening up again!?

Could also be the oil tank breather, gloop in the bottom of the oil tank, a plugged oil pump or blocked pickup strainer - check the easy ones before tackling the more difficult ones! -
Changing the rim isn't a magic way of getting faster cut speed. It will make a big saw on a small bar cut faster but may well make a saw on its usual bar size very boggy in the cut and cause over fuelling issues on tuned/auto tune saws by not allowing the saw to get in to it's powerband.
