Aussie wants advice on engine spec

[Knowledge]

I have recieved this enquiry from a guy in Australia. He uses most of the UK scooter dealers, but he wants advice on what to buy, and where to buy it:

What I have found difficult to find out is what are the Best Brand/s of after market parts for Lammy motor rebuilds....

As depending on which UK Lammy parts dealer you speak to you get - you will get a quite a range of answers and no two will give the same answer twice


I was expecting straight up answers like these are the best three Brands of :-

* Cranks - for balance and for strength

* Conrods - best length for what benefit

* Pistons - Super strong, Long wearing - won't hole out so easy that work well with what top end set up

* Electronic Ignitions

* HT Coils

* Mufflers - best Three for Touring & the best Three for Inner City / Hill climbing - Or work best with this Top End Kit & not so much another Top End Kit

* Bearings

* Oil Seals

* Gasket Sets

* Clutches

And the list goes on.....

How hard would it be for them to say,

The best two or three brands are X Y & Z - Brand X best for Motors over 20 Bhp and Brand Y for reliability and Brand Z not far behind on quality but over priced for what it is etc.


Right now I would love to Know which type Cranks work best when mated to What type of Pistons - and together work best and for what style of motor?

As the Right Piston (for quality / durability & it's weight) when Mated to the Right Crank will work better together as across the Rev Range they Zero Each Other Out and so will work really well together and not against each other.

Martin,

Right now I can walk into some of the better local GM Holden / Chevy spare parts shops and and they will show me charts that compare the different brands & types of Cranks to Conrods to Pistons to Cams - to find which parts work best when mated to what other parts to achieve the Best Result for what style of motor you are wanting to build.

I was hoping for similar advice as I'm happy to spend money to obtain the best possible result,

But when each shop seems to only want to promote their own brands of parts that they stock / carry - and it's difficult to know which way to go......

I Love Motors that are Balanced to the Point that each part works in with each other part to multiply the benefits and efficacy of the sum total of the parts.

You know how some motors just seem to "Sing and Run So Smoothly" while others seem to some how miss the mark and only do well in making a loud noise & bucket loads of vibrations.....

I hope to make Quality Motors that are Smooth, Quiet & as near to Vibration free as is possible for A Single Cylinder Two Stroke Lammy Motor

Please have a think and let me know what ever Brands that You Swear By as nothing beats listening to those who have Real World Hands on Experience


Many Thanks

Wayne

Any thoughts?

What did you advise .... Knowledge?
Looks like a load of questions with too many variable answers.
Of course dealer A will promote a certain product that they stock or manufacture. If I were selling GM parts then I wouldn't tell him he should go and buy a Ford product.
My advice would be to ask more specific questions about a particular set up to narrow down the variables somewhat.
He'll never get a straight conclusive answer in any event as everyone has an opinion and, as we've seen on this forum, the guys who really know their s**t have differing approaches.

Why can't he join a forum like everyone else? He can then read as much as he wants and draw his own conclusions.

They do have internet in Australia. There's even an Australian Scooter Forum.

I just told him the spec for my scooter, which is very, very basic.

There are certainly many variables here. His question is rather too large.

Yes, he needs to develop a relationship with a forum, though he admits to being wary of the many conflicting answers that forums can give (I think you'll agree that often this forum - and others - fail to reach a consensus)

On the contrary. I think all the conflicting answers on forums is a good thing. With a bit of experience, you can see the people whose advice and experience you largely share, and make judgements based on that when you're after advice yourself.
And.. it's always useful to hear what detractors have to say about anything.

Sounds to me like hes looking for the holy grail, hes looking for the truth.
But the fact is there is no truth only opinion, and you know what they say about opinions.
Alot of the stuff on the market thats sold as being "the be all and end all" just isn't. It very often doesn't fit straight out of the box and when made to fit it fails to deliver what was expected of it. Alot of stuff that works in one motor falls apart in another motor.
I think our aussie friend needs to join a few forums, read a few books/magazines spend huge amounts of money on crap that doesn't work and then after a few years he can form his own opinions on the subject.
Isn't that what we all have to do?
My list of dealers/parts I won't use anymore is alot longer than the list of those I will use.

SoundS to me like be is the ideal customer for a super Monza.

Mainly because the dealer will say its all matched and it's the best of everything. It's exactly what he wants to hear.
