Hidden power within my 1Y

[SplendiferousII]

About a year ago I fitted a 1Y engine to replace my 1.6na engine. Brilliant made all the difference in the world it would generally pull and extra 10mph everywhere and climb motorway hills without the need to drop it to third.

During the change out I had to modify my throttle cable mounts on top of the fuel pump. All was done nicely and I even got around to painting it before fitting.

But because I was working alone in my workshop I had to make do with blocks of wood to wedge the peddle down, to check the throttle worked when fully open.

Last night I had the van back in the shop with another person present. So I checked the throttle again and there was a little incy ikle little bit more movement left in the throttle arm.

So with a little twisting and bending of the brackets I adjusted this so that I now had full movement..

Not expecting much of an improvement I drove the van up the M5 to find she now pulled like a train. (relatively speaking here)

So I have gone from having lorries overtake me on anything other that the flattest, levelest roads to be able to keep with the lorries on the slight hills and pass them even on the flat to now passing them on the hills and actually having to throttle off when doing so as its all sounding a bit busy in the engine compartment.

The initial conversion was a marked improvement. Adjusting the cable was astonishing !

May be on the scrounge for some bike advice assistance

bought a Sachs ZX125---dont run--wiring issues and power valve not connected---it has previously been on fire.

What time are tall ships due to pass your work ?

Yes, the last part of the throttle on diesels can make a big difference... AndyS even modifies the pedal crank-pin, making it longer, to suit the pump arm travel.
Also, if the pump top has been off, the throttle arm/spindle registration can be out can even slip on the splines...

No problem just shout. Although not sure I'll be able to help much but will try.

The tall ships have been going past for tyhe last couple of days here. Are they supposed to be doing a run or something?

[weldore]

can someone post a pic of how they did the throttle lever conversion on the 1y pump after they changed from the 1.6..just so i can see if theres a better way than mine..unless theres a pic in the wiki...ill just check...
..oh i got about 4 mm more travel on mine ,not tested it with a run yet thought

[SplendiferousII]

I dont have my camara here today sorry. 4mm is quite a lot mine was only 2mm max.

Let us know how you get on.

[SplendiferousII]

Send me an email and I'll send you a couple I have here on my PC.

They are coming up the canal right now.

[weldore]

well, what can i say....it does seem a bit more punchier than before.

[SplendiferousII]

A bit more punchy is more than I found ! The only way I could tell the difference was driving my daily hack route to and from the office. Where it would pull 60 before it would now pull 70 that sort of thing. Feltthe same otherwise.

Sorry I did get your email. but to late as I'd left the office and I wont be there again this week.
