Misfiring GRiSO 8v 1200 (2009)

Sorry to hear about that Darrel, mine too needed a new bottom end, but was done at the same time as it had new rollers.

Somtimes life and motorcycling are shit, i am having the same problem with the car at the moment, worse than that, i hate the fucking thing, so it gets no sympathy at all

Well sometimes the golden eagle shits and you're standing underneath!

Slipped anew set of shells into Darrel's bike and fired it up today and, miracle of miracles, it's bottom end is now quiet! It's still incredibly noisy at the top end but it is a very early A5 motor and their top ends, even when rollerised, do tend to be noisier. I'm going to let it cool down overnight then I'll re-check the top end for fuck-ups during rollerisation but it may just be that it's a noisy sumbitch!

Anyway I'm pretty confident the bottom end is fixed and that was my main concern.

Pete

indeed! Get outa supermax Darrell.

It's still pretty vibey but the early bikes are, mine was when it had its original motor. I think they took a while to get the balance factors correct. Nothing like it was though, when it arrived it shook like a cheap sex aid.

Pete

I still have all fingers and toes crossed.

You'll be Golden Darrell, My 2009 GRiSO was rollered at about 34000 km, sounds a bit rattly, and has spent the last 2 years living on the rev limiter . No sign of an issue. These 8V engines are almost bullet proof

Outch. Just curious, at what mileage did this happen?

It was rollerised at about 60,000kms and it currently has 85,000kms on it Tim. Thanks also to all for your words and support, and Sidrat; I hope that car doesn't cause too much grief. I've been without a motorcycle now for about 4 weeks; its strange how that makes you a little depressed. on the flip side I've been lucky as my work said to take the work truck for as long as I need it - can't wait to give it back

Well I took it out for a 75-80km gallop this morning and did several full throttle to rev limiter runs through the gears and maxed it out at 200 which was terrifying as the suspension is so naff and it didn't throw a rod out of the side of the case so I'm calling it good.

It's still noisy from the top end but nothing seems awry, at least nothing I can't get to without stripping the top end so it'll just have to be a 'Suck it and see' job. I'm fairly confident it's good though.

Darrell picks it up tomorrow.

Pete

I picked the bike up in Bungendore yesterday morning and it ran well all the way back to Newcastle. The new shells have 541 kms on them now after the trip. It was a lovely day for a ride and for the first 70 or so I was escorted by Pete to Goulburn.
The revised Beetle map is unbelievably good and has really made the bike a lot more enjoyable. It revs freely and the actual gear changing has moved about 500 rpm up so its working in the rev range now where the bike is most comfortable.
Unfortunately just after leaving Pete I got a puncture in the rear tyre, so I had a very slow 50km run into Bowral where I knew there was a bike shop that could fix it. $20 well spent and I was on the road again, but I had lost a good 2-3 hours out of the day by then, so that meant a drone up the freeway home and Sydney traffic at peak hour through Pennant Hills Road. Pete said when I picked it up this was the worst case scenario for throwing a rod out the side of the case, it was 27 deg c, lots of stop start and idling. Eventually I got out and exited to the old Pacific Highway which was fun. The new map allows lot more precise throttle control which is enjoyable on the bendy bits.
I got home about 6pm and before I turned the bike off, I let it sit for a bit so I could listen to it without earplugs and helmet filtering it. There remains a lot of noise and clanking about, mostly its from the top, but there are some clunketty clunks from down below. So now its a wait and see what happens scenario. I might get a few weeks, a few months or few years out of it, but I do think at some stage there may be a need for a bottom end overhaul. Having said that I'm no expert in the 8V noise gallery. I may be just paranoid.
At any rate Pete has done a marvelous job resurrecting the bike and I am very grateful to him for that.[You must be registered and logged in to see this image.]

Darrell, you know Pete does the best thing for everyone, yourself included. It's probably OK, but as you say, keeping an ear out is a good thing. Park the paranoia - it'll do your head in.

Go ride mate.

Nice ballast Pete!



Note to self - don't look in the mirror, some (excess) ballast there too...

We'll have to see. As I said, it's a lot better than it was but without pulling the crank we don't know where we are and once we commit to that it's going to be big bickies.

We may get away with t just being noisy, as I said, I gave it a good work out and I'd of thought if anything was going to go tits ir would of done but we can't be sure.

Pete

Good to hear the bike's now running better, Darrell. Then to get a flat, with no plugs or pump handy, AND get Pennant Hills Rd in peak hour! Tough. I don't suppose we'll see you back down here anytime soon - it's going to take some time before THAT experience fades into vagueness. It could be up to some of us to head north instead - Al (the Saint) - couldn't make the Spag either - was enquiring about a re-visit to Long Flat or thereabouts.

Hey Mal,
Your'e right I have no desire to head south through that snarl again anytime soon. If its of any interest I have a place at Crowdy Head on the coast near Taree - Harrington. There is a good loop you could do from Sydney through to Gloucester and then buckets way, maybe with the Oxley on the run back the next day. The Lakes Way is also good if there is no traffic. Offers there anyway if you get any takers. I am a man of semi leisure in the new year so a mid week run could work easily. If it gets traction I'll flip this over to the cabals section.

I have a mate flying down from Cairns on the 7th for a couple of weeks, and it looks like we are going to call in to Wauchope for the Oxley bicentennial on the 17th. It might be better to stick him on one of the V7s rather than use his brother in law's BMW 310. And Al (the Saint - currently GRiSOless) was making noises about coming down soon. We'll have to check if Mr Bob is back from Oil & Gasistan, and Eric in Wauchope (yet another GRiSO) is trying to organise a spot at the celebrations for guzzis.

A cabal in the new year up that way sounds like a sterling proposition.

Darrell ,I live in Wingham,although Grisoless I do have an Audace. Im a fairly regular visitor to Crowdy lighthouse and work permitting always keen for a ride or an ale.....

I thought you'd kept the 1100 Charlie?

Pete

Gday Pete, unfortunately my financial state wouldnt allow it. But I think its gone to a good home in Brisbane. an 1100 Breva owner. He is pleased with it, although has yet to do the top end. By crikey I miss the GRiSO's.....but the Audace goes alright.

OK I'll move this thread now as it is way off topic to the cabals section. You can't miss my place Charlie, it has a crash helmet for a letter box and has a Moto Guzzi sticker on it. I'm not there often at the moment, but, next year that will change a bit. GRiSO update ............ it is getting quieter with riding! I think the previous owner had it in Sydney traffic a lot, so whilst my use is around town too, it gets to stretch its legs up the valley at least once a week which is doing it good.
