Series 2 With Jet engine

[Storkfoot]

Happy days.

Are you bothered about a warning lamp or do you think you'll have enough site of the indicators themselves?

This is the view from the seat. I had the warning light mocked up at the side of the switch. So, if I am going to be checking the warning light, I’ll see the indicator flashing anyway.



I’ll see how I get on without a warning light, or buzzer.

Nice job Paul

The S2 was “finished” three weeks ago. I dared to take it to my son’s wedding for photographs but it hadn’t done more than a couple of hundred yards on the road.

When I came back from the wedding, I went for a ride and felt that the gear change was a bit notchy. I quickly diagnosed that the selector arm bush was worn out. Given that the engine had all the tell take signs of being a very well used and abused one, I kicked myself for not spotting this in the first place. I also feared that I may have to drop the engine to fix it

Thankfully, I have managed to replace the bush after stripping out the gearbox and rear hub.







On the plus side, the Fresco sounds fantastic

I was putting the gearbox back in this earlier today. I noticed that the gear selector moved up and down on the Layshaft in each gear. I took the gear selector off and then found that the ball bearings were 7mm diameter and not 8mm as they should be.

Just thought I’d mention it as I dare say there are quite a few other undersized ball bearings inside layshafts if a dealer (I can’t remember where I bought the spring and bearings) has been selling the wrong size for some time.

No. Parkgate, South Wirral. Messing around with carburettor jetting again

WOW, THAT LOOKS LOVELY!

Thanks, mate

The jetting needs work. It’s a Chiselspeed Stage 4 tuned 200.

PHBL25 - throttle valve 300 or 350, pilot 48, slide 45, AQ270/ D29 2nd clip, 102 main. Filter is a bgm elbow with Marchald filter. It feels good, revs up and down crisply except for occasional bogging when accelerating. Plug colour on plug chops all the way through the range are pretty chocolatey brown.

At this point, I am torn between (a) at some point in the throttle progression, it is too rich and the excess petrol is hanging around in the bellows to then be sucked in when I accelerate, or (b) the slide is too lean. If I had an easily accessible dyno nearby, I’d get the air/ fuel ratio checked out.

Next, I am going to try a 40 slide which, I suspect will see me leaning the atomiser, at least.
