8)Ok guys I have a XL350 centre port (see last pic in "just a photo" post bike 775) with 38mm carb & big bore header, what's the next step in making the old girl go a little better, thinking 250 flywheel, cam (any suggestions) and a big bore kit, does any body know what piston fits.
Thanks

subaru piston :o

???What model subaru?
-
Bikes and Bits Importers in west aust can supply a wosner big bore piston kit,you will need a bigger sleeve to make a job of it.
I have the part no. here somewhere if you need it.
an inner rotor cdi will give you easy starting and almost eliminate the flywheel weight.

the old 1600 subaruwagon 4x4
i was told they do fit never tried it though
best ring ron or alan or luke at bikes and bits ;D

the guys at BBimporters are great! Very friendly, easy to deal with and very fast with orders. I ordered 2 bearings on wednesday and they came the next day, and i also ordered a rod kit yesterday and it came this morning.

Yer they are pretty cool.... 8)
When they rock up to an event they have everything to ride and everything to fix bits with...(not that they have bike troubles) :)
Down to earth fellow bike people, ;D and always have a smile on their dial. 8)
cheers

Nissan Skyline RB30 pistons also fit but are a bit on the heavy side. They give 420cc.
-

Is there a kit to do this change to CDI with innner rotor or do I make it up from bits, I have seen the odd post about pitbike CDI's being fitted with mix results.
Thanks guys all good information keep it coming how about a cam grind to suit.
-
bit of info here sudman on XL CDI

A quick hot up for them is to use an XR 350 std piston kit this takes it out to 408cc. The deck height is 2mm lower on the XR piston so you will need to machine 2mm from the base of the cylinder. You will need to use a new cam chain and guides. Also the valve reliefs need to be machined ( 0r ground) to suit the "Square" valves. I also machined a fair bit from the crank bells to lighten it. I did run a total loss ign using a bosch electronic off a V8 falcon. very acurate but had to use a heavy battery. This allowed me to remove the flywheel to recover the weight but made the engine too snappy.
-
isn't the XR400 piston a better bet than the XR350??,mates got one in his centreport 350,errr ,or was it a DR400 piston,duh,i'll have to check ::)

8)Now I know how to post a pic here she is.
-
wow nice bike, tank looks sweet. ;D
-
8)Thanks it was a bit of a mess when I got her been used as a river bike down Christchurch way, built by one of the guys from the Honda shop I am told back in the early 90's.
I hand formed the side panels, cleaned up the tank, fitted the slimmer seat, new pipe & plastics
-
Nice bike. 8)
What type/size bars do you have on that? They look nice and high.
-
Sorry I don't know the brand, the rise is 100mm, I have a black pair which are Ventura brand made here in NZ which are the same, the model stamped on them is 20U which does not appear on there website but they still make chrome bars & they look to be as high in the pictures so it would be worth asking the question.

Thanks Tony,
100mm? They look about twice that. I'll check that site out.
-
Yep 100mm to the bend & 130mm at the end of the bar, they do look about 200mm so I went out in the shed & checked again, they are the tallest set on any of the eight bikes.

Will an xl 350 engine fit into an xl or sl 250 frame with out any problems.
-
I know it will not fit in a XL175 just to big had look at that one a month or so ago >:(, but I am working on fitting one into a XLS 250 frame which is looking good just have to make the bottom rails up to suit the 350 engine, now all I need is a side port frame & motor so I can get on with my pre-75 project. :-X

A xl 350 side port fits straight in to a xl 250 moto sport frame.
Chris.
-
thank you chris, which would be the better frame to use. xl 350 or 250 for being the lightest or are they the same.
-
Hey Dave,
I've got a few XL250 frames and I think 1 XL350 frame amongst the pile, I think they are are all around '76 though. You can have one if you can use it.
Cheers,

The 250 and 350 frames are the same except the swing arm which is shorter on the 250.

This is the bit I find interesting?? Seems that if you ride a 250...it's said you should use the longer 350 s/arm. But if you ride the 350.....then you use the shorter 250 s/arm. ??? So I guess it all depends on riding style as to which you use?
-
just got (scored?? :-\) a TL250 roller off e bay,lets see if my XL350 motor is an improvement in that frame :P
-
I picked up a TL250 with the plan to repower it but it's to good a bike & a lot of fun to play on, so I now have SL250 frame for the 350 motor, got a set of light weight wheels, pd valves, works shocks, anyone got any ideas on taking the flex out of the old XL frames & swing arms?
