2T or 4T?

Postby CiderRider » Sat Jan 09, 2016 5:24 pm

Right lads I need some comments on which is better, 2T or 4T? I know some of you have have both (Ginger Phil!) and want your opinions please. I tried asking Eddie Bullet once and he said 2T for fun and tuning (not interested in playing with it only riding it) and 4T for commuting (won't be doing that either). This is purely for odd hour or two ride outs when and if it ever stops raining!

Right now all I can think is 2T you get the raspy quick revving and smell and sounds of a classic two stroke. So what are the benefits of a 4 stroke? No oil to buy and top up but what about service intervals? Is it faster? Better on long runs?

Look forward to hearing from you.

Cheers Lads...

4t for me had mind nearly 4 yrs and no real problems. Less chance of seizing etc... 3000 kms intervals for servicing. Go with what ever makes you happy. These days we have a lot of choice Auto, 4t or 2t. Ride safe.

classic design with 4t engine is what you require if you don't want to play with it. you can also get some really nice sounding exhausts to fit them so you don't have to sound like a 4t

Only problems with 4 strokes is if they go wrong, do you know anyone who can fix it where as with a 2 stroke if you're in a local club there will no doubt be loads of people who could fix it. I've had my 2t a year and had no engine probs apart from the coil so I think if you keep the 2t standard it should be OK. ;)

Having said all that, I'd love an auto LML. :mrgreen:

A mate in my club bought an LML 4T and after 4 months noticed that the frame was beginning warp. On examination it appeared that the frame was not strong enough for the heavy weight of the 4T engine. I have heard this a few times now and am aware that a few have gone back under warranty.

I have always gone with the 2T because as Phil said, there are plenty of us around who can get you out of trouble if needed. However, if you leave them alone and dont tamper you will get years and miles of reliable service. My clubs 1970's Vespa (which we use as a service scoot) goes first kick everytime and has been well around the clock!

Just some food for the proverbial ....

Funny you should say that as Mickey Boy had a stronger stand fitted to his 4t (the one I eventually bought) as he'd heard the same thing.

Am I wrong, but doesn't the engine always stay on the road so it's weight isn't likely to warp a frame. There've been loads of legitimate complaints/ faults levelled at the 4-t but this ain't one of them!
Also the engine isn't that complicated so don't be put off

4t engine sits in its own frame under the rear paneling, no burning on oil as per 2 stoke & less chance of seizing up. Had mine 4 years & looked after it & still like new.

Try both and see which you like the best.

A lot of posts talk about 2Ts as if they need an engine rebuild every 3 weeks. They certainly don't, they just keep going - especially if you are running standard and not tinkering with kits. Nothing wrong with good kits: as long as you set them up correctly.

I think the bigger decision is manual or auto..

I'm looking at a new 2T but not sure whether it will be ok for my 12 mile round trip commute. A large chunk of that would be ridden at 50-55, if it can do that for about 15 minutes. I have read that you shouldn't keep them at their top end for too long. I've also read a lot about seizing and problems which seems to make the 4T the better choice? The thing is I would prefer the 2T for the smell and sound and ease of working on. I had a derestricted (before it came in) standard Yamaha FS1E that was good for 65mph on a 49cc engine, a Kawasaki 350 and a Jawa 350, all 2t and none of those seized. I always rode with 2 fingers on the top of the clutch lever, but never had a problem. Should I be concerned? Should I go for a much more expensive Vespa with a bigger engine? Like the OP I don't want to tune the engine either. I also wouldn't mind the occasional longer trip, 40 miles for events on dual carriageways.

6 miles each way? That's nothing chap. You only have to give a 2 stroke a breather every 30 or 40 miles.

Well Ciderider,

Don't know about you but this thread convinced me to go for a 2T. I'm having it derestricted from new. Ive posted a pic of the new wheels on the general section.

Cheers,
BR

Another plus point for the 2T, all the legacy extras such as seats will fit.

12 miles is nothing. 2Ts generally only sieze when modified to the limits of their power and/or the jetting isn't quite right. The 2T at 150cc is basically standard tune.

Any 2T will seize is they are fucked about with and set up badly.
Apart from that its a hardy robust beast that will give you a whole lot of raaaasp and a whole lot of freinds in the scooter scene.

The 4T is a great idea and will keep us in scoots for years to come but this old dog is a bit long in the tooth for change now. My 29 years of 2T have not been
wrong (so far) and I have them in my blood. The smell, the sound, the ease of working on and the people all do it for me.

Love your scoot no matter what it is - just be safe.
